There are too many steps in this castle, and it seems to me they add a few every night, just to vex me" - Maester Cressen

The gods don’t care about men, no more than kings care about peasants.

Valar Morghulis - All men must die.

For they are the knights of summer, and winter is coming.

A dead enemy is a joy forever

There is no creature on earth half so terrifying as a truly just man.

The sun will soon be setting, and corpses make poor company by night. These were dark and dangerous men, alive. I doubt that death will have improved them.
